Function Documentation

void Util_shake_init	(	util_shake_ctx_t *	c,
		uint8_t	output_length
	)

Initialises a SHA3 context object

Parameters

c	Pointer to pre-allocated SHA3 context object
output_length	Length in bytes of intended Hash Function output

Definition at line 116 of file shake.c.

void Util_shake_update	(	util_shake_ctx_t *	c,
		const uint8_t *	data,
		uint32_t	data_length
	)

Adds input data to a SHA3 context

Parameters

c	Pointer to allocated & initialised SHA3 context object
data	Input data buffer
data_length	Length of the input data buffer

Definition at line 129 of file shake.c.

void Util_shake_out	(	util_shake_ctx_t *	c,
		uint8_t *	out
	)

Produces output of SHA3 context.

Note: This should only be run once for an initialised context object.

Parameters

c	Pointer to allocated & initialised SHA3 context object
out	Output data buffer
